I am a new 4s user and several times when I access siri, she hesitates and then says "I am sorry about this, but I can't take any....." What is up with this? Thanks in advance..
Just kidding - Siri requires a connection to the server to work. You might be in an area where reception is poor or the server might be overloaded. Sometimes toward the end of a business day - probably when more people are using Siri, I have trouble getting her do respond or maybe she's just had a hard day?
